Selectfluor-triggered C–H halogenations of enaminones with copper(I) halide (CuX) for the synthesis of 3-halochromones
A practical and efficient synthetic route to construct a variety of 3-halochromones has been realized using Selectfluor reagent as a fluorine source, or Selectfluor-copper(I) halide combination as halogen source under mild conditions. This reaction proceeds via a sequence of electrophilic cation addition, and cyclization leading to a broad range of 3-halochromones in good to excellent yields in a short period of time. Additionally, the utilization of commercially available and cost-effective Selectfluor and copper(I) halide renders this system highly practical.
